Called the 888 number and was told of this
They definitely need your passport (or PRC ID) number, but I've never been asked to send them a copy of my actual passport. I always book on Ctrip, which has my passport number. I never bother with advance seat assignments, and have never ended up in a middle seat, but even if I did, it wouldn't be the end of the world for my 2 hour flights.
